This research deals with the validation of fluid dynamic models, used for simulating shoaling and breaking solitary waves on slopes, based on experiments performed at the Ecole Supérieure d’Ingénieurs de Marseille’s (ESIM) laboratory. A separate paper, also presented at this conference, reports on experiments. In a first part of this work, a fully nonlinear potential flow model based on a Bound...

The rise and deformation of a gas bubble in an otherwise stationary liquid contained in a closed, right vertical cylinder is investigated using a modified volume-of-fluid (VOF) method incorporating surface tension stresses. Starting from a perfectly spherical bubble which is initially at rest, the upward motion of the bubble in a gravitational field is studied by tracking the liquid–gas interfa...

Abstract With the development of simulation technology and programs, it became necessary to study models that control equations’ solutions influence results. The having over solving equations multiple phases materials are investigated. They include (Volume Fluid (VOF), mixture, Eulerian) controlling governing equations. was conducted depending on boiling point water. activation these three is c...

Large-eddy simulations have been conducted for two-phase flow (water and air) in a hydrocyclone using Two-Fluid (Euler–Euler) Volume-of-Fluid (VOF) models. Subgrid stresses are modeled dynamic eddy–viscosity model, results compared to those the Smagorinsky model. The effects of grid resolutions on mean turbulence statistics thoroughly investigated. Five block-structured grids 0.72, 1.47, 2.4, 3...

In this paper, an HLLC-type contact preserving Riemann solver for incompressible two-phase flows using the artificial compressibility formulation is presented. This improvement over previous HLLC-VOF (Bhat and Mandal, 2019). work, unlike formulation, variation of volume fraction taken into account when calculating eigenvalues eigenvectors. Hence, equations intermediate states wave speed are clo...

We present a fully compressible single-fluid volume of fluid (VOF) solver with phase change for high-speed flows, where the atomization liquid can occur either by aerodynamics or effect local pressure. The VOF approximation among non-miscible (non-condensable gas) and mixture two fluids (liquid vapor) represents core jet its atomization. A barotropic model is used in combination equation state ...
